Filter by:This randomized study investigates the benefits of an additional Bispectral Index monitoring of depth of sedation during endoscopic retrograde cholangiopancreaticography. A bispectral index (BIS) monitor is a neurophysiological monitoring device which continually analyses a patient's electroencephalograms during general anaesthesia to assess the level of consciousness during anaesthesia.
The purpose of this study is to determine whether a non-pharmacological intervention reduces consumption of sedative drugs during colonoscopy. A reduction of sedative drugs may reduce side effects. This non-pharmacological intervention may increase patient's comfort and security.
The purpose of this study is to evaluate the safety and effectiveness of a study medication that contains a combination of a pain medication, sufentanil, and a sedative, triazolam. This drug is being designed to provide mild sedation as well as reduce anxiety and pain before and during a procedure (in this case elective abdominal liposuction).
In intensive care unit, patients suffered pain and anxiety from mechanical ventilation, presence of endotracheal tube, central venous catheter, postoperative wound, and invasive procedures. Adequate analgesia and sedation can reduce pain and anxiety. However, traditional sedatives carry the risk of unstable hemodynamic status, respiratory depression, increased mechanical ventilation time, incidence of delirium, and length of ICU stay. Dexmedetomidine is a highly selec¬tive α2-adrenergic receptor agonist which causes sedative effects and reduces opioid requirements in the perioperative period. Memis et al had found that dexmedetomidine may prevent inflammatory effects in sepsis patients during sedation. Oxidative stress status is related to the inflammatory response. Moreover, oxidative stress may result in dysfunction of microcirculation. Dysfunction of microcirculation may cause vasoconstriction or microthrombosis, and it will impair tissue perfusion and result in organ dysfunction. The goal of this study is to compare the effects of dexmedetomidine and midazolam on requirement of analgesics, weaning parameter, hemodynamic status, time of extubation, incidence of delirium, and length of ICU stay, oxidative stress status, and microcirculation.
The investigators believe dexmedetomidine will provide superior sedation with reduced side effects and reduced time to discharge compared with pentobarbital. The investigators have developed sedation protocols with pentobarbital and dexmedetomidine in our ambulatory procedure center. These protocols are both routinely used for sedation in our unit. The investigators propose to study these two protocols in children ages 6 months to 6 years presenting to the ambulatory procedure center for non-painful procedural sedation. The investigators will compare failure of sedation, side effect profile, recovery and discharge times between the two pharmacologic protocols.
The purpose of this study is to evaluate the safety and efficacy of dexmedetomidine (DEX) in intubated and mechanically ventilated pediatric intensive care unit (PICU) subjects. The key study objectives are: - To characterize the loading and maintenance dosing of DEX by age group and overall medical condition of pediatric subjects - To evaluate the safety and efficacy of loading and maintenance infusions for sedation in initially intubated and mechanically ventilated PICU subjects - To explore the exposure-response relationship between dose of DEX and clinical measures of sedation and safety
The purpose of this study is to correlate the cerebral state index obtained from a cerebral state monitor with the Richmond Agitation-Sedation Scale assessment performed on sedated and mechanically ventilated intensive care patients.
Assess impact of increasing dose of dexmedetomidine on total daily dose of fentanyl and propofol while maintaining sedation in a mechanically ventilated patient in a general medical intensive care unit.
-to determine if propofol sedation leads to shorter recovery times compared to traditional sedation using midazolam plus meperidine
In a recent study by Yuen et al it was shown that preoperative intranasal administration of dexmedetomidine is a useful alternative for oral midazolam in children. However, there is no information on the pharmacokinetics of dexmedetomidine after intranasal administration. The aim of this study is to investigate the comparative pharmacokinetics of intranasally and intravenously administered dexmedetomidine in healthy volunteers. The absolute bioavailability of intranasally administered dexmedetomidine will be calculated. In addition, we will report the effects of intranasally and intravenously administered dexmedetomidine on plasma catecholamine levels, systemic blood pressure, heart rate and sedation. We will also monitor the local and systemic safety and tolerability of intranasally administered dexmedetomidine.
